Application flled February 17, 1925. Serial No. 9,825.

This invention relates to driers but more particularly to driers of the type adapted to receive disk-like articles, such as can ends or covers which have previously been coated 6 with a liquid or semi-liquid lining material.

Objects of the inventionare to rovide drying mechanism whichis adapte to receive a relatively great number of disk-like articles and convey them from one end to the 10. other .where they are discharged with the new and improved features of construction and arrangement hereinafter described.

In the drawings,

Fig. 1 is a top view of the drier shown in Fig. 2; and

.Fig, 2 is a vertical sectional elevation of the drier.

The embodimentof the invention chosen for the purpose of, illustration comprises a drier having inner and outer, upright, concentric cylinders 10 and 11 which are spaced from each other a suitable distance to provide an annular drying chamber A. The inner cylinder 10 is preferably provided at one end with an integral tubular extension 12 which may be mounted in a sleeve-like support 13, relative movement between the tubular extension 12 and support 13 being prevented by a screw 14. Formed on the outer periphery of the cylinder 10 is a continuous spiral thread 15 providing a track for one edge of the can ends B as will hereinafter be described, the spirals of the thread preferably extending in the manner indicated.

The outer cylinder 11 may be secured 11'). any suitable manner to a plate or disk 16 which may be provided with an integral sleeve 17 surounding the tubular extens on '12, the lower end of the sleeve 17 hearing against the support 13. For rotat ng the cylinder 11 a beveled ring gear 18 1s fixed to the under-surface of the plate 16, and a beveled pinion 19 meshes with the r ng gear 18', the ring gear 19 being fast to a shaft 20 which may be driven from any suitable source of power such as an electr c motor.

Any suitable means may be provided for heating the interior of the drying chamber; as shown, a burner 21 extends into the tubular extension 12 and apertures 22 are formed 1n the cylinder 10 so that the heated air passes therethrough into the drying chamber A thereby acceleratin the evaporation of the liquid component in the lining material wh ch has previously been applied to the can ends B. 5

In the operation of the drier can ends B are fed in any suitable or preferred manner to the slide 23 which extends a slight distance into the drying chamber A and in this manner the can ends are conducted to the spiral track or thread 15. The space between the two cylinders is less than the diameter of the can ends B so that in the drying chamber A they assume an inclined position with the outer edge bearing against the inner surface of the cylinder 11 and the in ner edge engaging the track 15. By rotating the cylinder 11 in the manner described it will be apparent that the can ends B arerolled along the spiral track or thread 15 with a curvilinear motion from the upper end of the drying chamber A to the lower end where they will fall therefrom through an opening 24 in the plate 16. While being propelled through the chamber the heat generated by the burner 21 hastens the drying of the li uid or semi-liquid coating on the cover so t at as discharged from the drier this coating is completely (or partially) dried.

A cardinal feature of the invention consists in'the provision of a drier having a spiral track on a wall of the drying chamber to receive one edge of the can ends, the opposite portion of the ends hearing at an angle against the opposite wallof the chamber, so that by rotating one of the walls the can ends are carried to travel through the chamber. A drier'constructed in accordanee with the invention is simple, efficient and is capable of handling large numbers of can ends at one time without liability of 1amming;

\Vhile I have described my improved machine in more or less detail to comply with the requirements of the statute, it is never theless desired that this detail description be considered merely as illustrative and not aslimited, and it is to be understood that changes in modification may be made by those skilled in this art without departing from the invention, especially as defined in the following claims.

I claim:

1. A drier comprising an annular drying chamber having means to admit can ends thereto, a spiral track on a Wall of said chamber to engage one portion of the can ends, another portion of the can ends resting at an angle against the opposite Wall of the chamber, and means to rotate said opposite wall thereby to propel can ends along said track from one end of the chamber to the other.

2. A drier comprising an annular drying chamber having means to admit can ends thereto, a spiral track on the inner Wall of said chamber to engage a portion of the can ends, another portion of said ends resting at an angle against the outer wall of the chamber, and means to rotate said outer wall thereby to propel can ends along said track from one end of the chamber to the other.

3. A drier comprising an annular drying chamber having means to admit can ends thereto, a spiral track on the inner Wall of said chamber to engage a portion of the can ends, another portion of said ends resting at an angle against the outer Wall of the chamber, means for heating the interior of said chamber, and means to rotate said outer Wall thereby to propel can ends along said track from one end of the chamber to the other.

4. A drier comprising concentric cylinders having means to admit can ends into the space'therebetween, a spiral track on one of the opposed surfaces of said cylinders for supporting one ed e of the can ends, another portion of the en s resting against the surface of the adjacent cylinder, and means to rotate the outer cylinder thereby to propel can ends from one end of the drier to the other.

5. A drier comprising an annular drying chamber having means to admit can ends thereto, a spiral track to engage one portion of the can ends, another portion of the can ends resting at an angle against an opposite support, and means to rotate said support thereby to propel can ends along said track from one end of the chamber to the other.
